In FriCAS documentation build directory means directory where
you run 'configure'. 'build', 'src' and 'target' are just
subdirectores of the build directory. If you do in source
build, then you also have source stuff (mostly in 'src' poluting
build directory).

Well, they are really templates so that user can customize them as
needed. We could do the substitution and put the result in the
contrib subdirectory of the build tree. However, after installing
FriCAS user may delete build directory, and both use things that
are not part of normal installation. I guess that for ECL we
could add extra target building shared library (library should
be usable without build tree, it only depends on files in final
installation). But sbcl part was really for people who want to
tweak it.

'mk_shlib.lisp' is ECL-only. I guess I should change
"Works with ECL." into "Works only with ECL."
